Time, instantaneous frequency, accumulated phase (radians)
Linear f=f0+(f1−f0)t/T; logarithmic f=f0 exp(log(f1/f0)t/T); integrate exactly.

Assumptions & limits
Assumptions & limits
- Start-end frequencies, duration, sweep law. Returns Instantaneous frequency and phase. All coefficients and observations are user supplied; results describe only the stated mathematical model. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Start frequency (Hz): minimum 1e-12, maximum 1000000000000.0. End frequency (Hz): minimum 1e-12, maximum 1000000000000.0. Sweep duration (seconds): minimum 1e-12, maximum 1000000000000.0. Sweep law: 0 linear; 1 logarithmic: minimum 0, maximum 1. Schedule intervals: minimum 1, maximum 128.
